The purpose of this research study is to determine whether a 12-week telehealth aerobic exercise intervention is feasible in people with epilepsy.
The study team will also gather information on the effect of the intervention on sleep and stress as mediators of seizure frequency, well as effects on epilepsy and epilepsy associated comorbidities.
This is a randomized, controlled pilot trial to assess the feasibility and fidelity of a 12 week, individualized, telehealth exercise intervention in people with refractory epilepsy. This will be carried out using a 2 arm, parallel group design with a waitlist attention control.
Participants will undergo formal exercise testing prior to enrollment to determine safety and establish a baseline fitness level. Participants will use a wrist-worn Garmin device to record activity and sleep. After a 4 week baseline period, participants will be randomized to intervention or wait-list attention control. The intervention group will undergo a 12-week telehealth exercise program designed by a trained health coach and tailored to the individual's personal fitness level and exercise preferences. The intervention is based in social cognitive theory to implement and enforce sustainable behavior change. The wait-list attention control will receive health education but will not be given an exercise program. At the end of the intervention period, the control group will be given the option to participate in the exercise program.
The study will assess recruitment and retention as well as fidelity, acceptability and sustainability of a telehealth exercise intervention in this population.
The study will investigate objective and subjective measures of the effect of the intervention on the known seizure triggers of sleep and stress as possible mediators of seizure frequency.
The study will collect information regarding the effects of the intervention on depression, anxiety, quality of life, cognition, and seizure frequency.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Exercise Intervention | Experimental | Participants in this arm will be enrolled in a telehealth-delivered exercise program with the goal of progressing to 150 min/week (5 days per week, 30 minutes of steady state walking per day). Participants will meet weekly 1:1 with a trained health coach via a Webex platform. Weekly exercise goals will be tailored to the individual's abilities and specific barriers. Coaching will utilize social cognitive theory and self-determination theory to develop self-efficacy for sustainable behavior change. |
|
| Control | Active Comparator | Participants randomized to the wait-list attention control group will continue to undergo standard care for 12 weeks. They will continue to wear the Garmin activity tracker and can view their activity but will not be given an exercise program. They will be contacted by a study coordinator via telephone every 2 weeks for health education. During this time, they will review resources and healthy lifestyle guidelines for people with epilepsy, including healthy diet, medication compliance, seizure precautions, stress management, and sleep hygiene. |

Due to the nature of the intervention, participants will not be blinded as to whether they are in the intervention or control group.
Blinded study staff will perform all pre-and post outcome assessments. The PI will also be blinded
| Health Coach | Behavioral | The coach will work directly with each participant during their once-weekly virtual 1:1 meeting to progress intensity and duration. Participants will meet with the coach to review a brief social cognitive theory-based module, which will provide education on core behavior change concepts and the benefits of physical activity for those with epilepsy. The coach will review the previous week's exercise during meetings, and will then work with the participant to revise and reset goals for the coming week. |
|
| Health Information | Behavioral | Participants will be contacted by a study coordinator via telephone every 2 weeks for health education. During this time, they will review resources and healthy lifestyle guidelines for people with epilepsy, including healthy diet, medication compliance, seizure precautions, stress management, and sleep hygiene. |
|
| Acceptability of the Intervention Questionnaire | This will be a qualitative measure based on post program question of how satisfied the subject was with the exercise intervention with a scale of 1=Very Unsatisfied, 2=Unsatisfied, 3=Neutral, 4=Satisfied, 5=Very Satisfied. Results will include percentage of people who answer 4 or above. | Week 16 and Week 28 after baseline |

| Exercise Self-Efficacy Questionnaire (EXSE) | Items on all self-efficacy questionnaire that ask participants to rate their confidence on a 100-point percentage scale such that 0% corresponds with "not confident at all", and 100% corresponds with "highly confident", and scale scores are generated by averaging all items in the scale. Higher scores represent greater self-efficacy. | baseline, week 16 after baseline, week 28 after baseline |
| Exercise Goal Setting Questionnaire (EGS) | This questionnaire assesses participants' ability to set and meet goals relative to exercise behavior by asking how closely a series of statements describes them (e.g., "I usually set dates for achieving my goals") on a 5 point scale such that 1 corresponds with "Does not Describe" and 5 corresponds with "Describes Completely". A total scale score was generated by summing all items, with possible scores ranging from 10 to 50 with higher scores reflecting greater goal setting behavior | baseline, week 16 after baseline, week 28 after baseline |
| Multidimensional Expectations for Exercise Scale (MOEES) Physical Score | This 15-item questionnaire assesses the three dimensions of outcome expectations for exercise (i.e., physical, social, and self-evaluative). Participants are asked to rate the degree to which they agree with statements relating to outcome expectations (e.g., "Exercise will increase my muscle strength") on a 5-point scale. Three subscale scores will be generated. Physical scores range from 6 to 30 with higher scores indicating higher levels of outcome expectations for exercise. | baseline, week 16 after baseline, week 28 after baseline |
